Question

раскройте скобки 1)3(2а+b-8c) 2)-4(-x+3y 4z) 3)(m-5n-6k)*(-1.4) 4)(-a-3.4b+3c)*(-d) 5)-0.8a(4p-5b-1.2) 6)-14(3/7x-9/14y+0.5z-0.2)

Answer 1

1. 3(2a+b-8c)=6a+3b-24c
2. -4(-x+3y*4z)=-4(-x+12yz)=4x-48yz
3. (m-5n-6k)*(-1,4)=-1,4m+7n+8,4k
4. (-a-3,4b+3c)*(-d)=ad+3,4bd-3cd
5. -0,8a(4p-5b-1,2)=-3,2ap+4ab+0,96a
6. -14(3/7x-9/14y+0,5z-0,2)=-6x+9y-7z+2,8
